Thankyou CSI Kitchen and Bath! Do you have a specific color you think would work?

I think a linen look floor to ceiling pinch pleat drapery with a decorator rod that complement the mantel would look beautiful.

Would you recommend a white linen?

White/linen was the first thought I had. It would also look nice to use a darker shade like the above picture and a white or linen sheer in the center section. If you were to do this I would recommend painting the wall white so the dark color would not show through the sheer above the window in contrast to the window.

I would say a creamy/off white.

White linen pinch pleat would be perfect, you could even add a design tape along lead edge.

Thankyou everyone!
